I am taking apart an engine, which is a 998 incase that makes any difference.

Basically i've taken apart everything, apart from the crankshaft pulley bolt (timing chain end) which seems to be bloody well stuck on. So, before i take a lump hammer to it i'd like to know i'm trying to turn it the right way.

At the moment i'm assuming it is a standard anticlockwise-to-undo thread. Any dismantling tips would be appreciated.

Cheers!

Yes it is a normal right handed thread. The pulley bolt is fitted with a lock washer which is hammered around the flats of the bolt, I take it you have straightened out the lock washer?

Then if you have already separated the flywheel from the crank, and removed the transfer case, then just remove the gearbox as well, and lock the crank with a suitably decent sized piece of wood, and use a socket and breaker bar...

Yeah, i've flattened that out.

Guessworks, it's stripped down to the block with crank,cam and timing gear remaining. I tried your method, the problem now being that i can't hold the block still enough when turning the socket.. i guess i'll have to find some way of bolting it down.

Thanks for the help.

Strap the block onto a big wide piece of thick plywood with some ratchet straps. Don't do them up too tight accross the open areas of the block as you can easily snap the block with these straps. Similarly when the crank is locked up with wooden blocks apply steady pressure to the breaker bar until it moves rather than hammering it. It really is easy to punch a hole in the soft grey iron block. Try to lock all of the crank webs with blocks of wood if the bolt is really tight in order to spread the load around the cylinder block as much as possible.
